JOHN F. KYTLICA, OF CHICAGO, ILLINOIS.

VALVE MECHANISM.

To all whom it may concern:

Be it known that I, JOHN F. KYTLIoA, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Valve Mechanism, of which the following is a specification.

This invention relates to improvements in valve mechanism or construction, and particularly to such mechanism designed for use on internal combustion engines of the T- head motor type, although it is applicable for use in connection with other types of engines and for other uses, and for this reason I wish it understood that I do not limit myself in its use or application, but may employ it wherever it may be found practicable.

The invention consists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof as Will be hereinafter more fully set forth and specifically claimed.

In the type of engines or motors above mentioned, as heretofore constructed, lift or puppet valves operated by the pressure of the gases or of the atmosphere, or by suitable cam mechanism and springs have generally been employed, and experience shows that such valves are open to many objections, among them, the uncertainty of operation attendant upon springs or other non-positive returning means, and the noise produced by the operation of the parts.

One of the objects of the invention is to provide means for controlling the admission and exhaust of the motive agent or fluid and the burned gases or inert fluid, respectively, which shall obviate the objections abovereferred to, and which shall be simple and inexpensive in construction, strong, durable, and efficient in operation. Another object of the invention is to provide valve mechanism of such construction that it can be used instead of the commonly employed puppet valves without material change in the engine head construction. Still another object is to provide a self-lubricating valve mechanism provided with means to cause the valve casing to wear evenly and to expand as the casing becomes worn, thus preventmgleakage. A further and very lmportant ob ect is Specification of Letters Patent.

Application filed March 13, 1918. Serial N 0. 222,062.

to provide reciprocating or sliding piston valves with means for their positive, uniform, and noiseless operation, and so that Very high speed of the engine may be obtained with the certainty that the charges of the motive agent into the compression chamber and a thorough direct exhaust of the exploded products from said chamber will occur regularly at intermittent intervals. Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In the accompanying drawings which serve to illustrate an embodiment of the invention- Figure 1, is a vertical sectional view showing a portion of one end of an internal combustion engine of the T-head motor type with my improved valve mechanism located in one of the valve casings thereof, said view being taken on line 1, 1, of Fig. 2.

Fig. 2, is a plan view partly in section and partly in elevation taken on line 2, 2, of Fig. 1.

Fig. 3, is a detached perspective view of the detachable barrel or cylinder of the mechanism, and

Fig. 4:, is a similar view of the washer used for holding certain packing rings in position.

Corresponding numerals of reference refer to like parts throughout the different views of the drawings.

The reference numeral 5, designates a portion of the engine cylinder which may be provided with a water jacket 6, and spark plug 7, of the ordinary or any well known construction and arranged or located in the usual manner. In the present instance, a part of an engine of the T-head type 1s shown with one valve mechanism only therefor as the other would be a duplicate and consequently it is unnecessary to show and describe it. For the sake of explanation and description, it will be assumed that the valve mechanism shown in the drawings is for the control of the inlet of motive fluid, but it will be understood that the valve for the control of the exhaust of the engine is of the same construction and operation. In an internally screw threaded bore or opengage ing 8, in the lateral extension 9, of the head of the engine is located an externally screw threaded barrel or cylinder 10, which has near its inner end a plurality of ports 11,-

which extend circumferentially with respect to the said barrel or cylinder and communicate, one or more of them directly with'th'e compression chamber 12 of the others communicate with a circumferential groove or enlargement 13, on the inner surface of the lateral extension 9, of the cylinder head. This circumferential groove 13, communicates with the compresslon chamber 12, as is clearly shown and will be readily understood by reference to Fig. 2, of the drawings. As will be seen by reference to Fig. 1, of the drawings, the extension or 4 valve casing 9, is provided in its portion op posite the open end of the. bore or opening therein with a port 14, which in the present instance is the inlet port of the engine. In wardly of the port-14, the casing or extension 9, is provided with an annular valve seat 15, the face or wall of which is inwardly and downwardly tapered as is usual in the construction of valve casings where puppet valves are employed. In fact, the valve casingvor extension 9, in its self is of the ordinary engine construction employed in T-head engines but the cage and puppet valve usually employed are omitted or. dispensed with and my improved barrel or cylinder 10,'is used instead of said cage and acentrally apertured plug or block'16, having its surface adjacent to the valve seat 15, shaped to correspond with said seat is employed in lieu of the puppet valve but for a different purpose.

This block or member '16, is circular in shape and hollow in its lower portion and is mounted on or made integrally with a sleeve 17 which sleeve is centrally located in the shown in Figs. 1 and 2,.of the drawings, the

block or member 16 is united to the sleeve by means of radial arms 23, and is of sufli cient size at its portion adjacent to the'valve seat 15, to fit closely in the barrel or cylinder 1.0,so as to prevent leakage. As a; further meansfor preventing, leakage an annular gasket '24, of leather or othersuitable'materialfm'ay be :lnterposed' between the valve seat 15,'and the surface of the block'l6yad the engine, while jacent thereto. The upper portion of the block 16, or that portion thereof opposite the seat 15, is provided with a transverse floor 25., whichcloses the cavity of said block or member and said floor or partition is provided. onits outer surface with an annular extension 26, terminating at its free edge in an outwardly extended flange 27, which vis of less diameter than the cavity of the cylinder10, or barrel. This construction of the upper portion of the block 16, or that portion thereof opposite the seat 15, provides an annular recess 28, in the outer surface of the partition 25, inwhich recess the innerportion of the Washer 22, is movably located. As shown inFi'g.1,of the drawings the Washer 22, has a recess 29, in'its' central outer portion and'isprovided at its periphery with an annular-fla-ngeBO, sur rounding the flange 27, of the partition=25, of the block 16, but in loose engagement therewith. The-s ring 21. is located inthe recess 29, and rests atone of its ends against the washer 22 and at its other end against the nut 19, by means of which nut the tension of said spring can be regulated so as to afford the desired pressure to the, washer.- The block or member 16, is provided with an annular channel or recess 31, whichextends from the-flange 27, thereof to a point near that partof said blockormember which contacts'withthe barrel 10,-as at 32, near the seat 15, of the extension 9, or valve ca s; ing. Located in the channel 31, oneonthe other are packing rings 33 and 34, which are transversely split or broken at diametrically opposite points to permit of expansion and contraction. The packing rings 33, or'th'eouter one is provided at its edge adjacent to the flange 30, with a shoulder 35, against which said flange will rest so as'to press said ring against the opposite wall of the channel 31, in which said rings are located. It will be observed by reference to Fig. 1,

of the drawings that the portion-of the ring 33, adjacent to said flange is reduced as at 36, and that a circular space 37, between said ring and the barrel 10, is provided in which the piston valve-38, is adapted to operate.

This valve is cylindrical in shape and is provided on its periphery with a number of annulargrooves 39, for the distribution of a suitable lubricant and is mounted on one end of the operating'rod 40, which extends through the sleeve 17, and may be reciprocated in any suitable manner, but in the present instance I have shown it as being adjust ably connected by means of a screw plug-41,

to the stem. 42,"of a yoke 43, theprongs 44c,

of which stride. a disk 4:5, mounted on the camshaft'46,"of the engine. Each of the prongs 44:, of the yoke has an inwardly ex tended shaft 4:7,"each provided-witha roller 48, which shafts and "rollers are adapted to travel in cam grooves 49, on opposite faces of the cam disk. The screw plug 41, engages the threads of a recess 50, in one end of the stem 42, and said plug has in its outer end a screw threaded recess 51, which is reduced at its inner end as at 52 which construction forms an annular shoulder 53, on which will rest the members of a split washer 54, which fits around the reduced portion 55, of the operating rod 40, which sired position by means of a lock nut 58,

mounted on said collar. By this coupling arrangement it is apparent that the rod 40, will be swiveledin the plug 41, and that said plug can be suitably adjusted with respect to the stem 42, by turning it in the proper direction, and that it may be locked in the desired position by means of a lock nut 59, mounted on the plug 41. The outer surface of the barrel or cylinder 10, is screw threaded to engage the. threads of the extension or casing 9, and also to engage a cap 60, used for closing said barrel or cylinder, which latter is provided in its outer end with a circumferential groove 61, which commu-v nicates with a groove or channel 62, extended longitudinally in the wall of the barrel. The channel 62, communicates at its inner end with an' annular groove 63, on the inner surface of the barrel 10, near the ports 11,

therein. The cap 60, isprovided with an opening'64,ywith which a pipe 65, leading from a lubricating supply communicates, which pipe may be coupled to the cap 60, by means of a suitable coupling 66. By this arrangement it is apparent that oil can be supplied" to the groove 61, in the barrel .10, and that it will pass from said groove through the channel 62,.into the groove or channel 63, from which it will be distributed on the walls of the piston valve and barrel through the medium of the channels 39,. in said valve. The end of the piston valve 38, adjacent to the cap 60, is provided with openings 67, to prevent vacuum in the valve chamber. The valve 38, is provided. near its end adjacent to the cap 60, with an annular groove 68, in which are located interlocking packing rings 69 and 70, to prevent leakage. The packing rings 33 and 34, are provided. with ports 33 and .34, respectively, to register with the ports 11 in the barrel 10, and with the ports 16*, in the block 16 as will be clearly seen and understood by reference to Fig. 2 of the drawings.
